INSECT-EXTERMINATOR.

' Specification of Letters Patent.

Application led June 16, 1908. Serial No. 438,871.A

To all whom it may concern:

Be it known that I, WILEY FAnEsT NAN- NEY, a citizen of the United States, residing at Ben Franklin, in the county of Delta and State of Texas, have invented .a new and useful Insect-Exterminator, of which the following is a specification.

Thisl invention relates to insect destroyers and more particularly to a machine for catching and destroying cotton boll weevils.

It is a well known fact that cotton boll weevils pierce the unripe cotton bolls and deposit their ovum therein, thus rendering the bolls faulty so that the latter soon fall to the ground where they usually remain until the ovum develops.

The object of the present invention is to provide a machine which will gather the affected cotton squares and bolls and deposit the same in a suitable receptacle from which they may be removed and destroyed.

A further object f the invention is generally to improve this class of devices so as to increase their utility, durability and sciency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.v

' In the accompanying drawingsforming a part of this specification: Figure 1 is a perspective view of a machine for destroying insects constructed in accordance with my invention. Fig. 2 is a vertical sectional view of the same.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings. j

The improved machineforming the subject matter of the present invention comprises a wheeled truck including an axle 5 having oppositely disposed traction wheels 6, the latter being keyed to the axle and adjustable longitudinally thereof so that the machine may travel between rows of dierent widths.y Surrounding the axle 5 are spaced sleeves or collars 7, the latter being connected with the shafts or thills 8 and provided with anti-friction balls or rollers thereby to reduce friction between the-parts. Ex-

tending transversely across the shafts in spaced relation to the axle 5 are supporting bars 9 upon which is mounted a tank or receptacle 10 adapted to receive the affected cotton bollsy and squares as the latter are gathered from the ground between the different rows of growing` plants. Y

Mounted on one of the transverse bars 9 is a fan casing 11 having a shaft 12 j ournaled therein" and on which is mounted for rotation a suction fan 18. One side of the fan casing 11 communicates with the interior of the tank or receptacle 10, while the other side thereof is provided with a depending pipe 14 carrying a suction tube 15, the latter being connected with the tube 14 by a Hexible coupling member 16.

Secured to the lower end of the depending tube 15 is a suction head or hood 17 preferably conical in shape and into which the dead cotton bolls, squares and insects are drawn and deposited in the receptacle 10 whenV the fan is rotated. The shaft l2 is provided with a beveled gear 18, which latter. meshes with a corresponding beveled gear carried by a counter shaft 19. The counter shaft 19 is journaled in suitable bearings 2() and is provided at its outer end with a sprocket wheel 21, loosely mounted on the shaft 19 and connected through the medium of a sprocket chain 22 with a relatively large sprocket wheel 23 loosely mounted on the axle 5.

Arranged adjacent to the sprocket wheel 23 is a clutch member 24 having a hand operated lever 25 by means of which the sprocket wheel 23 may bev clutched' to the axle andthereby transmit motion from said axle to the suction fan. A clutch member 26 is also preferably mounted on the shaft 19 for engagement with a corresponding clutch member carried by the sprocket wheel 21 so that the fan Inay be rotated independently of the axle if desired.

The clutch 26 is provided with an operating lever 27, the intermediate portion of which is pivotally mounted on a standard 28 carried by an arm on the adjacent cross bar 9 and terminates in a suitable linger piece by means of which the lever may be operated to actuate the clutch 26.

The receptacle 10 is provided with an 01T set portion 29 defining a chamber 30, which latter communicates with the interior of the chamber 10 but is separated therefrom by a strip of wire fabric or other foraminous material 31 so that as the air is forced into the interior of the receptacle 10 by the action of the fan the cotton bolls, squares and insects vwill Vstrike the strip 31 and bev deflected downwardly within the receptacle thereby to prevent the entrance of the same into the compartment 30.

Communicating withy the opposite ends of the compartment 30 are tubes 32 having flexible portions 33, the free ends of which are provided with inwardly extending discharge nozzles 34 through which the blast of the air from the fan 13 passes so as to blow any insects or affected cotton squares or boils from the growing plants as the machine travels between the several rows of said plants.

Depending from one of the bars 9 is a rod or hanger 35 on the lower end of which is pivotally mounted a drag plate or deflector 36, which latter, serves to receive the impact of the cotton bolls and squares as the same are blown from the plants by the action of the blast of air from the discharge nozzles 34. llhe upper longitudinal edge of the plate 36 is inclined in the direction of the hood 17 and is provided with oppositely disposed downwardly inclined wings 36 for deflecting the bells and insects downwardly and in the path ot movement of the suction head or hood whereby they may be conveyed to the receptacle l0. Disposed in advance et the deflector 3G are depending rods or shakers 37 having inwardly extending arms 38 which travel over the growing cotton plants and serve to agitate the same and thus assist. in dislodging the faulty cotton bells and squares so that they will be deposited on the ground by the action of the blast of air from the nozzles 34, The flexible portions of the air tubes are normally and yieldably supported in operative position by suitable coiled springs 39 each having one end thereof secured to the tube 33 and its opposite end anchored in any suitable manner to the shafts 8, as shown.4

The tank 10 is provided with a pivoted section 40 which latter forms a closure for the tank so that by moving the door 40 to open position the contents of the receptacle may be readily removed thereby to permit the affected cotton bells and insects to be readily destroyed.

Secured to and extending laterally from one of the transverse bars 9 is an upwardly inclined bar 4l to the tree end of which secured a seat 42 to accommodate the driver. Suitable pawl. and ratchet mechanism 48 is also provided for permitting reverse movement ot the traction wheels when backing the machine.

As a means for elevating the suction hood or head 17 a cord or cable 44 is provided, one end of which is secured to the head while the opposite end thereof extends over a pulley 45 mounted for rotation on the bar 41 and provided with a terminal finger piece within easy reach of the drivers seat, there and drag plate or deflector 3G, whereby said plate and hood may be elevated simultaneously, as shown.

T he operation ot the device is as tollows: The machine is drawn between rows growing cotton plants with the agitators 23S traveling over the plants ot opposite row:-' and with the nozzles -l-i discharging a blast ot' air against said plants. )rs the machine travels, motion will be imparted Vfrom the M- aXle through the medium ot the sprocket chain Q2 and shaft ll to the fan thus rotaiing the latter and causing the blast ot air from the fan to be directed downwardly through the tubes 32 and discharge nazi/.les 34 onto the plants to dislodge the inserts and affected cotton squares and boils. the plants having been previously agitated by the action oi the shakers in the manner before described. The suction created by the Vtan in the pipe 14 will draw up the insect-1 and a'tiected cotton squares and bolls and deposit the same within the receptacle l0 'trom which they may e removed and burned or otherwise destroyed atter the rc eptaele is iilled or partially filled.

From the foregoing description, il is thought that the constrnetimi and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.
